Stereo noise thru speakers: help
Just in the last few months I have noticed a "white" noise kind of
sound when I have the stereo on when in moderate to loud volume.
It is very noticable like when listening to morning radio when they go
from music to talk/ quiet time..
I thought that maybe a new alternator might solve it since My Alternator
bearing was sqeaking anyway , but that made no difference.
Car is 2000 vert w/ stock single disc cd player and stock bose
speakers.
Please tell me where to look

Hmm stock system and new noise. My guess is that the HU is on its way and sending some noise through to the factory amp that is audible when the volume is up. Usually most of this type of noise originates from poor grounds and/or signal wires near power wires. Could be a few of your grounds are a bit corroded and need a little cleaning. That is where I would start first. Might want to post in the audio/electronics section as well some knowledgeable people there.

White Noise
This may sound silly, but:
I too have the phantom noise, more pronounced on AM stations.
Even asked the dealer about it when I had the car in for some other issues.
Dealer could not replicate the problem because the only time it does it is when
I have my cell phone in the car and turned on.
Discovered this by accident because I forget my phone one time and realized the noise was gone.
As I pass between cell tower coverage areas, the noise is kind of like a white noise Morse Code.
Also, a second or two before I receive a call, the noise will be louder and constant.
This also happens in the DD (1995 Impala SS).
Hope this helps...............

I have the same morse code noise, but had dismissed it as a factory amp on its last leg. It could explain some of our problems.
